Shadowsword source book?

[Warsmith Shaughn]

Hello, my buddy is tempting me to add a Shadowsword super heavy tank to my Iron Warriors list; but what's the best source book/rules to use for adding a tank like that to a CSM list?
The Volcano cannon is a D weapon yeah?
Thanks for any advice <o

The best book I have with the Shadowsword in is the MontKa second book - there are some really good formations in there.

Yes the Shadowsword fires a D weapon.

However I think the faction is Astra Militarum, which by the book is Come the apocalypse allies for Chaos Marines. As such, you would be an unbound list and also are obliged to deploy it over 12" away - which may be more difficult due to its huge footprint.

I may have that wrong though.
